Stochastically modelled multidimensional crossplots,which account for uncertainty in rock and fluid properties
(based on petrophysical analyses of well data), were used to build 2D probability density functions (AI vs Vp/Vs).
These were compared to crossplots of equivalent inverted seismic data to make predictions and quantitatively update
the geological model. Individual probability volumes as well as a most-likely lithology and fluid volume were generated.
